 improve check of -wno-* compiler flags
 The GCC documentation says that unrecognized warning options in the -Wno-* form
 do not cause errors unless other diagnostics are issued. And thus unsupported
 flags may be appended. This results in a failed build when there are some false
 positive warnings.
